Back lit acrylit panel

[YPF]

Customer has given me a 600mm x 600mm x 7mm acrylic panel that has been painted on the reverse. He wants the panel back lit to highlight the painting. The panel came with some cheap stand offs (chromed plastic painted grey) that go through a much small diameter hole than other stand offs I have seen (from Lion, for example). So I will have to find something to cover the holes in the panel.

We agreed a narrow, deep profile aluminium frame, hoping that this will allow a lighting system to be fitted between the acrylic and whatever backing I use.

My greatest concern is being able to provide enough light across the surface of the panel without causing any hotspots of light. Advice from an LED supplier would be to use 4 x 500mm lines of LEDs equally spaced with a diffuser over each line, cost for this was nearing 3 figures. I have also looked a the possibility of a ready made light panel (with diffuser) but not sure of their depth yet.

Has anybody done this sort of thing before and able to offer some advice?

Many thanks.

I did a stained glass window and the structure went like this:

Backing panel made of mirrored acrylic
Led strips fixed on their side to furniture blocks glued to the mirror
Space (about 40mm)
An acrylic panel covered with diffused vinyl
The stained glass window


Looked the business, with no hot or cold spots

I'm about to do 10 light boxes for a customer done the same way, obviously without the stained glass!

Abacus - that sounds like it could a less expensive option than those I have found so far. Would you mind if I gave you a ring?

I recently did one for an artist who supplied a panel 600 x 600 which are designed as emergency ceiling lighting panels - gave very even light with no hotspots and is dimable but cost approaching £100. don't have the info to hand but could ask her if you are interested.

Was just about to post the same question. I have someone wanting a variety of sizes framing with internal lighting (could be up to 1200 mm square)
Can anyone recommend a supplier of the led strips please?
Thanks

There's loads of them on ebay such as

Had spotted this, thanks. This may sound stupid, but are the lights (or can they be) battery powered?

The ones I use are 240v using a control unit.
